Technology is great when it starts to empower people, rather than just make companies money. Here is an Indiegogo campaign for a small battery operated device that, when dipped into a beverage, can detect whether your drink has been drugged. It’s called the pd.id. (personal drink ID).
It is small (it looks like a USB device), is reusable, can identify in some cases the actual drug and you can use it on it’s own (it has a green and red light that light up after it has “read” your drink) or with a smart phone.
For more information and to back this campaign (until August 29th, 2014) go to Indiegogo.com.
